New York, NY -- (SBWIRE) -- 01/20/2015 -- Radiation therapy is the treatment using ionizing radiation to control, shrink or kill malignant cells. Gamma rays, x-rays and charged particles are radiations mainly used for cancer treatment. Linear accelerator (LINAC) systems, gamma knife and proton beam therapy are the types of radiotherapy. Gamma knife is a non-invasive radiation therapy, to treat tumor and other brain abnormalities. It is also known as stereotactic radio-surgery. It is used mainly for the treatment of pituitary tumors, arteriovenous malfunctions, brain tumors and brain dysfunctions such as trigeminal neuralgia, acoustic neuroma and epilepsy. In gamma knife radio-surgery specialized equipments are used to focus close to 200 gamma beams of radiations. These highly focused beams together converge to deliver powerful treatment for a single point on a tumor. It damages the cancer cells and prevents them from multiplying. In addition, it minimally damages the healthy tissues surrounding the target. It is done by fitting a frame on the head, as to keep the head steady during the treatment. It has low side effects compare to other radiation therapies and conventional surgery. Some of the early complications of gamma knife surgery are fatigue, swelling and scalp and hair problems. In rare cases later complications such as neurological problems may also appear. It is a onetime therapy completed in a single day. The treatment effect of gamma knife radio-surgery appears gradually depending upon the condition. In benign tumors, it results in failure of tumor cells to reproduce. Similarly, in trigeminal neuralgia, it helps to block the transmission of pain signals along the trigeminal nerve. In arteriovenous malformations gamma knife surgeries thickens and close off abnormal blood vessels of brain.

North America dominates the global market for gamma knife due to large number of aging population. Asia is expected to show high growth rates in the next five years in the global gamma knife market. China and India are expected to be the fastest growing gamma knife markets in Asia-Pacific region. Some of the key driving forces for gamma knife market in emerging countries are large pool of patients, increasing healthcare expenditure and rising government funding.

In recent times there is increased use of gamma knife due to increasing incidence of tumors. Rise in aging population, increasing prevalence of brain abnormalities, healthy reimbursement policies and increased government funding are some of the key factors driving the growth for the global gamma knife market. In addition, increasing healthcare awareness is also fuelling the growth of global gamma knife market. However, alternative treatment procedure and lack of adequate healthcare infrastructure are some of the major factors restraining the growth for the global gamma knife market. In addition, high cost involved for treatment with the help of gamma knife is also inhibiting the growth of the global gamma knife market.

Increasing healthcare expenditure would lead to growth in gamma knife market in Asia. However, lack of skilled and trained professionals and side effects of gamma knife surgery could be a lead challenge for the global gamma knife market. Some of the major companies operating in the global gamma knife market are Elekta AB, Variant Medical Systems ET Medical, Hokai Medical, Huiheng Medical, Nordion, Ion Beam Applications and Accuray Incorporated.
